What is the final temperature, 80 kJ energy given to pressure cooker, mass 4 kg,30°C, specific heat is 1000 J/ kg°C.
1 Answer
Given,
mass m = 4 kg
initial temperature t1 = 30°C
sp. heat capacity = 1000 J/kg°C
final temp t2 = ?
Heat Q = 80KJ = 80000 J
by the heat equation,
we knowthat,
Q = msdt
80000 = 4 * 1000 * (t2-30 )
t2 = 50 °C
